Specification forming part of Letters Patent No. 40,46%

To all whom it mag/concern.'

Be it known that I, SAMUEL GARDINERJ r., of the city, county, and State of New York, have invented a new and useful Improvement in Explosive Projectiles for Muskets and other Small-Arms, as also for Cannon of Small or Large Caliber; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure lis a side view of an explosiveshell for muskets and other small-arms. Fig. 2 is an end view of the same, showing the fusechamber. Fig. 3 is a longitudinal sectional View, representing the shell, ready for lling. Figs. 4 and 5 are perspective views of the two pound. Fig. 6 is/af'sectional View of the said representinga small hole in each end, through which a mandrel is inserted to support the cup in the center ofthe mold. The said mandrel also forms the small hole leading from the fuse to the chamber which holds the explosive substance or compound.

Similar letters of reference in each ofthe several figures indicate corresponding parts.

The nature of my invention consists in manufacturing musket and other small-arm shells, forming and casting the shell complete and at one operation, which is done successfully by forcing the heated metal into the mold by a force-pump placed in connection with the The machineis similar to a squirt used by type-manufactur the shells is lead or any other material that will expand enough to lill the grooves of the gun, and at the same time, when the explosion takes place, to break into several parts.

, explosion, as the -mixture can be so arranged as to explode in one; two, three, orV more seconds. Explosive caps may also be used to set 'iire to the explosive material. They are not safe to handle or transport. Therefore I recommend fuse instead.

To enable others skilled in the art to make .and use my invention, I will proceed to describe its construction and operation.

A is the body of the shell, made of lead or any othermaterial which will iiow freely into the mold. i

B is the inside chamber for holding the eX- plosive substance or compound. It is made of copper or any other mtzterial. l

C is the cavity which holds the fuse matcrial.

D is the small hole leading from the fuse C to the inner chamber, B. A cartridge is attached in the usual manner to the shell. When the musket or gun is fired, the powder ignites the fuse, which will onds, as the time of burning the fuse may have been arranged. When the explosive materia-l in the cup is ignited, the shell immediately explodes. l

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y l Constructing shells for lire-arms by forcing the metal into the mold around an internal shell, B, supported o n a hereinbefore described.

In testimony of which invention I hereunto set my hand.
